2. Fast intermittent
Periodic fasting is a diet that alternates between fasting and eating.

There are several ways to do an intermittent fast, including a diet of 5: 2, a 16: 8 method, and an Eat Stop Eat method.

In general, these methods consume fewer calories in total, without the need to deliberately limit the amount of calories during a meal. This should lead to weight loss, as well as to many other health benefits (38).
